You can create an xml file like this:
<source lang=text> <ColorMap name="Consistency" space="RGB">
<Point x="-1.000" o="1" r="0.0" g="0.0" b="0.0"/> <Point x="0.000" o="1" r="0.0" g="1.0" b="0.0"/> <Point x="1.000" o="1" r="1.0" g="0.0" b="0.0"/>
</ColorMap> </source>
which specifies that values=-1 should be black (rgb=(0,0,0)), values at 0 should be green, and values at 1 should be red. You can then click "Edit color map" -> "Choose preset" -> "Import", select the new xml file, and you will see the colors are interpolated along the new color axis you have defined.
